Old lenses were very 'slow' (pick up a camera from even the 1930s,
you'll find they often didn't go any faster than say f/5.6).
Old photographic processes weren't particularly fast ("high ISO")
either.
If you're sitting for a photo in natural light, and the lens is slow,
and the medium is slow, you may have to sit for 30 seconds. I, for one,
cannot maintain a good smile for 30 seconds when I'm posing for a
picture. It's a lot easier to sit stone-faced.
